The way I see it is like this:
He ended with $42.15 -- the last thing that he did before that was buy the umbrella
$42.15 + $23.75 (umbrella) = $65.90
The next thing backwards in order is that he spent "half of his remaining money on a painting", so what he has left...

The way that I would solve this problem is by graphing both the purse snatcher (thief) and the police officer, and the point where they intersect is where the officer catches up to the thief. The y-axis can represent how many meters were run, and the x-axis can represent how many seconds it has...

When you're solving an equation for a variable (in this case x) you are trying to get
x on one side of the equal sign all by itself. To do that, you do the
opposite of what is being done to it (so that you can get the number in front of the
x to equal 1). So when you have:
17 x = -85
x...

General Information:
For x2 ± # x ± # you have a ( x ± # )( x ± # ) The two numbers at the end have to
add together to get to # x and have to
multiply together to get to the ending #
When you have a number in front of the x2 that number...

In the phrase "Please Excuse My
Dear Aunt Sally" each first letter stands for an operation like this "Parenthesis
Exponents Multiplication OR Division
Addition OR Subtraction".
So, in a problem, you look first for parenthesis -- 12÷2(6-7+4)x2 -- then you solve what...

It is a well known fact that most students don't have school over the summer. As a tutor, that usually spells disaster (unless you have a second, steady job). I personally, work two jobs -- unfortunately, both of them are freelancing jobs (tutor and backstage tech), so I don't really have any work over the summer. You have to keep up motivation, or else you're doomed to failure. Especially because...

A brief history of me:
So, usually I teach older students -- freshmen in high school through college kids. That's worked out really well for me, during the school year when lots of college students needed help. Unfortunately, it's summer now. My main job working as a backstage tech at the Chandler Center for the Arts had no calls for me to work, so I was dead broke, needing to pay rent and...

Well! I just realized that in 2 more hours (one more after today) I will have hit my 50 hours of Tutoring Completed mark! To honor this momentous occasion, I decided to write about my experiences here so far!
When I first started out with WyzAnt.com, I was in a crunch. I had gotten into a scooter crash, and could not walk because my knee and ankle were covered in deep road rash. Since I couldn't...

Okay!
So, I haven't posted in a while, and it's best to keep updated, right?
Well, Spring 2012 semester, I took my first Education class at Chandler-Gilbert Community College.
First things first ... they made us get an $85.00 state finger print clearance card that all teachers are REQUIRED to have, and that is valid for six years. If you want to see, let me know before hand.
Secondly,...

One of the things that I have taken an interest in lately has been the differences between schooling ten or twenty years ago compared to schooling now. The main difference is, of course, technology! My boyfriend's geology teacher who has been teaching something like 60 years likes to share a story with his classes; he explains about when he first started teaching (using slide rulers) and how he...

Hi! I'm Katie D. and I haven't tutored anyone through this site yet, but I am really excited to get started!
In high school, I took honors, advanced placement, and International Baccalaureate classes, I was part of the freshmen orientation comity (LINK Crew) for three years, and I volunteered my time whenever I could. I tutored Rebound students who had failed two or more classes in general...
